Creative Biolabs offers first class custom PEGylation services that are based on next-generation PEGylation technologies.PEGylation is the process of covalently attaching one or more chains of PEG [Poly(ethylene glycol)], also known as poly(ethylene oxide) (PEO) or polyoxyethylene (POE)], to a protein molecule, thus creating a PEG-conjugated protein. Therapeutic proteins are either rapidly degraded, have a short circulating life, or are rapidly excreted when introduced into the bloodstream.
